Kidney Disease a Surprising Reason For Hearing Loss

Kidney Disease: A Surprising Reason for Hearing Loss

When visiting Hearing Unlimited, you may be surprised to hear us discussing the state of your kidneys with you – but we have good reason to do so! Read out the full blog post.

When visiting Hearing Unlimited, you may be surprised by the various health conditions we discuss with you during your hearing tests. That’s because our practice doesn’t just treat hearing problems. Instead, we use the latest healthcare research to provide feedback on your hearing and the health risks your hearing may share a connection with.

We take this approach because many hearing issues share symptoms or risk factors with other health conditions. Last month, for example, we explored how your ear doctor can be a part of your heart health care routine. This month, we’re exploring a potentially more surprising link – hearing loss and kidney disease.

What is Kidney Disease?

26 million American adults have chronic kidney disease (CKD). Millions of others are currently at risk of developing this health issue. CKD causes damage to the kidneys over time, leading to eventual kidney failure. Symptoms tend to appear slowly, however. Without early detection, patients are at a higher risk of developing complications due to reduced kidney function. And since the kidneys are responsible for helping to filter waste out of our bodies, those complications can be messy – even dangerous.

CKD is often a result of conditions such as diabetes and high blood pressure. However, at Hearing Unlimited, we’re most interested in the similarities between kidney disease and the ears. Because, believe it or not, they do share some things in common.

What’s The Connection?

If you asked a medical professional about the kidneys and the ears, they would tell you that “the kidneys share physiologic, ultrastructural and antigenic similarities with the stria vascularis of the cochlea.” Or, in plain English: a specific part of our ears shares functional and structural characteristics with our kidneys.

It almost sounds unreal – how could the ears share similarities with the kidneys? But research has confirmed that physiological mechanisms of fluid and electrolyte balance are present in both organs. This matters because it means that when a health issue affects the functionality of one (i.e. the kidneys or the ears), it’s likely to affect the other. So while hearing loss doesn’t cause CKD – or vice versa – patients with certain types of hearing loss are likely to experience problems with their kidneys (and vice versa).

Research at this time also confirms the correlation between these health issues. In one study, 54.4% of patients with moderate CKD had measurable hearing loss. That’s much higher than the control group. In that group, less than 30% of people demonstrated measurable hearing loss.

What are Some Risk Factors To Watch For?

The most common shared risk factors for CKD and hearing loss include:

  • Age (older patients are more at risk of these conditions)
  • A diabetes diagnosis (which can impact both the ears and the kidneys)
  • A hypertension (i.e. high blood pressure) diagnosis (which puts extra strain on the heart and kidneys)
  • The use of certain medications with side effects known to impact the functionality of the ears and/or the kidneys

Additionally, a diagnosis of hearing loss and/or CKD – and the treatments used to address both – is likely to increase the chances of a patient developing the other condition.

What Does This Mean For You?

  • Don’t smoke. Smoking can limit blood flow to all of your organs, increasing your risk of kidney and ear problems.
  • Control your blood pressure. High blood pressure can weaken and/or harden the kidney and ears’ blood vessels, impeding their functionality.
  • Eat well. A healthy diet rich in vegetables and fruits, and low in saturated fats and added sugars, is well known to support healthy bodily functions all around.
  • Exercise frequently. Exercising is the best way to help keep your heart healthy (and reduce your risk of high blood pressure and diabetes.)
  • Have your doctor test you for kidney and heart disease. In addition to living a healthy lifestyle, it’s important to screen for these health issues so that they can be addressed as early as possible should they develop.
